Abstract

Boost half bridge DC-DC converters in the combination of an input-series and output-series (ISOS) connected configuration with a stable control strategy has been investigated in this paper. A stable control strategy comprises of two loops that are current loop and voltage loop. The reference to the current loop has been chosen from the input side of the DC-DC converter. The reference to the voltage loop has been selected from the output side of the DC-DC converter. Such a reference makes the circuit configuration simple, easy and eventually results in reduced cost. The control strategy for input-series output-series (ISOS) configuration of DC-DC converters is proposed to achieve equal input voltage sharing (IVS) as well output voltage sharing (OVS). Furthermore, in this paper, the performance of the stable control strategy for input-series output-series (ISOS) boost half bridge DC-DC converter has been observed not only for the fixed but also for the varying and continuously varying load. The proposed Stable control scheme has been developed by modeling it on MATLAB using Simulink and Simpower toolboxes. The operation of the proposed stable control strategy has been found to be satisfactory.DOI : http://dx.doi.org/10.11591/telkomnika.v12i1.3098
